Rig Veda
तयो॒रिदम॑व॒च्छव॑स्ति॒ग्मा दि॒द्युन्म॒घोनो॑: । प्रति॒ द्रुणा॒ गभ॑स्त्यो॒र्गवां॑ वृत्र॒घ्न एष॑ते ॥ तयोरिदमवच्छवस्तिग्मा दिद्युन्मघोनोः । प्रति द्रुणा गभस्त्योर्गवां वृत्रघ्न एषते ॥
Overpowering is the might of these two; the bright (lightning) is shining in the hands of Maghavan, as they go toether in one chariot for the (recovery of the) cows and the destruction of Vṛtra.
